Converting unit and USB-adapted peripheral apparatus

Abstract

Connected to a CD-RW drive ( 30 ) having an IDE apparatus interface ( 31 ), a speech apparatus output terminal ( 32 ), and a power supply apparatus input terminal ( 33 ), a converting unit ( 20 ) has an IDE unit interface ( 21 ), a speech unit input terminal ( 22 ), a power supply unit output terminal ( 23 ), a USB unit interface ( 24 ), a speech unit output terminal ( 25 ), and a power supply unit input terminal ( 26 ). The converting unit ( 20 ) comprises an IDE/USB converting circuit ( 27 ) connected between the IDE unit interface 21 and the USB unit interface ( 24 ). The IDE/USB converting circuit ( 27 ) carries out an interface conversion between an IDE interface and a USB interface. The converting unit ( 20 ) further comprises a noise filter ( 28 ) connected between the power supply unit input terminal ( 26 ) and the power supply unit output terminal ( 23 ). The speech unit input terminal ( 22 ) is directly connected to the speech unit output terminal ( 25 ).
